Hashtable与 HashMap类似,它继承自Dictionary类,不同的是:它不允许记录的键或者值为空;它支持线程的同步,即任一时刻只有一个线程能写Hashtable,因此也导致了 Hashtable在写入时会比较慢。 LinkedHashMap 是HashMap的一个子类,保存了记录的插入顺序,在用Iterator遍历LinkedHashMap时,先得到的记录肯定是先插入的.也...

Resizable array list (List<T>) 当元素的数量不是固定的,并且需要使用下标时。 Stack (Stack<T>) 当需要实现 LIFO(Last In First Out)时。 Queue (Queue<T>) 当需要实现 FIFO(First In First Out)时。 Hash table (Dictionary<K,T>) 当需要使用键值对(Key-Value)来快速添加和查找,并且元素没有特定的...

The only recommendable linked list scheme is inlining the key or hash into the array. Nowadays everybody uses fast open addressing, even if the load factor needs to be ~50%, unless you use Cuckoo Hashing. I.e. the usage of SipHash for their hash table in Python 3.4, ruby, rust, ...
